Angular SPA cannot open remote SSRS report - asp.net

Question

thanks to all for your time and efforts trying to help me solve this.
Now lets get to it... I have an AngularJS SPA. I would like to provide links on my view page, that when clicked, open a new tab and launch pre-existing SSRS reports in PDF format. Technically what I am trying to do: Render an SSRS report in my Repository, pass that through my WEB API then on to my SPA for display in a new tab.
One important note before I go any further: This setup, method, approach works flawlessly on my local machine within Visual Studio. It's when I move my SPA to a remote Web server (the same server that hosts SSRS) that I have a problem.
My Landscape:
Local Development Machine (Windows 7 Pro, VS2015 Pro)
Server1 (Win Server 2012R2): Hosts IIS (8), SPA, SQL (2014) and SSRS
Server2 (Win Server 2012R2). Hosts SSRS (SQL 2012) source of data (happens to be SSAS cubes, but I don't think that matters).
On My Local Development Machine:
As stated above the solution works fine through Visual Studio. The only part of the solution on my local machine is the SPA. The SSRS and SQL portion are located remotely. I can launch my SPA, click on a link and new tab opens containing the PDF report. I can also make a call directly to the web API and display a PDF report (http://localhost:3040/api/dataservice/ProductivityReportH/)
Problem 1
Browsing to the deployed version of my SPA on Server1, the application displays fine. But, if I click on a report hyperlink I get a the following message:
Do you want to open or save ProductivityReportH/ (3.28KB) from Server1?
No matter what I click (Open, Save, Cancel) nothing happens.
If I try and launch the report directly through the API, I get the same message. There are no errors displayed in the console window. I could find no errors in the Server1 log files.
On Server1: I can display the report via the SSRS report viewer.
Problem 1A
Using a browser on Server1, I can display the application just fine. But, if I click on a report hyperlink I get the same message as Problem 1. If I try to launch the report directly through the web API (http://Server1/projecttracker/api/dataservice/ProductivityReportH/)
on Server1, I get the same message.
Any ideas would be greatly appreciated
My SPA Setup:
View Page:
<div class="view indent">
<div class="container">
<h2>Productivity Reports Method 1</h2>
<a ng-href='#here' ng-click="hproductivityreport()">Launch</a><br>
</div>
My Controller:
(function () {
var ProjectsController = function ($scope, $window) {
$scope.hproductivityreport = function () {
$window.open('api/dataservice/ProductivityReportH/', '_blank');
};
}
ProjectsController.$inject = ['$scope', '$window'];
angular.module('ReportTracker').controller('ProjectsController', ProjectsController)
}());
The WEB API:
using ProjectTracker.Repository;
using System.IO;
using System.Net;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Web;
using System.Web.Http;
namespace ProjectTracker.Model
{
[Authorize]
public class DataServiceController : ApiController
{
IProjectTracker _ProjectTrackerRepository;
public DataServiceController()
: this(null)
{
}
public DataServiceController(IProjectTracker Repo)
{
_ProjectTrackerRepository = Repo ?? new ProjectTrackerRepository ();
}
[HttpGet]
public HttpResponseMessage ProductivityReportH()
{
var result = new HttpResponseMessage(HttpStatusCode.OK);
byte[] bytes = _ProjectTrackerRepository.RenderProductivityReport("Hibble, Norman");
Stream stream = new MemoryStream(bytes);
result.Content = new StreamContent(stream);
result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/pdf");
return result;
}
}
}
The Respository:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Data;
namespace ProjectTracker.Repository
{
public class ProjectTrackerRepository : RepositoryBase<ProjectTrackerContext>, IProjectTracker
{
ProjectTrackerContext _Context;
public ProjectTrackerRepository()
{
_Context = new ProjectTrackerContext();
}
public Byte[] RenderProductivityReport(string _sManager)
{
Server1.ReportExecutionService rs = new Server1.ReportExecutionService();
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
rs.Url = "http://Server1/reportserver/ReportExecution2005.asmx";
// Render arguments
byte[] result = null;
string reportPath = "/Staff Client Services/StaffProductivity";
string format = "PDF";
string historyID = null;
string devInfo = #"<DeviceInfo><Toolbar>False</Toolbar></DeviceInfo>";
//Create the list of parameters that will be passed to the report
List<Server1.ParameterValue> lstParameterValues = new List<Server1.ParameterValue>();
Server1.ParameterValue aParameter = new Server1.ParameterValue();
aParameter.Name = "SupervisorSupervisorName";
aParameter.Value = "[Supervisor].[Supervisor Name].&[" + _sManager + "]";
lstParameterValues.Add(aParameter);
Server1.ParameterValue bParameter = new Server1.ParameterValue();
bParameter.Name = "PayPeriodPayPeriodYear";
bParameter.Value = "[Pay Period].[Pay Period Year].&[2015]";
lstParameterValues.Add(bParameter);
int index = 0;
Server1.ParameterValue[] parameterValues = new Server1.ParameterValue[lstParameterValues.Count];
foreach (Server1.ParameterValue parameterValue in lstParameterValues)
{
parameterValues[index] = parameterValue;
index++;
}
string encoding;
string mimeType;
string extension;
Server1.Warning[] warnings = null;
string[] streamIDs = null;
Server1.ExecutionInfo execInfo = new Server1.ExecutionInfo();
Server1.ExecutionHeader execHeader = new Server1.ExecutionHeader();
rs.ExecutionHeaderValue = execHeader;
execInfo = rs.LoadReport(reportPath, historyID);
rs.SetExecutionParameters(parameterValues, "en-us");
String SessionId = rs.ExecutionHeaderValue.ExecutionID;
try
{
result = rs.Render(format, devInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);
execInfo = rs.GetExecutionInfo();
}
catch (Exception e)
{
Exception Errr = e.InnerException;
}
return result;
}
}
}

Finally! For those that are interested...
Found this from nearly two years ago.
AppPool Permission Issue with Accessing Report Server
In particular the comment below:
Almost the same situation here except IIS and Report Server running on Windows Server 2008 R2. I used to have the asp.net application running with it's own application pool and everything worked. When I changed the application to the DefaultAppPool (due to a different problem), I got the permissions problem. I changed the Identity of the DefaultAppPool from ApplicationPoolIdentity to LocalSystem (in IIS, Advanced Settings) and it worked again.
Changed web server default app pool to LocalSystem and wha-la, I am rendering PDF reports from an SSAS cube through my AngularJS SPA.
